Running issue related to alternator

A 92 Turbo with Electromotive twin plug. Performance has gradually degraded over the past few months but comes and goes. One minute it will improve if you unplug one of the coil packs and then later will degrade while running on one set of coils but improve if you plug the coil pack back in. Is Nuts. My post is about what is needed from the alternator. I am seeing 13.6-7 V at the battery and 13.4-5 V back at the DME. The erratic pattern feels like a ground but the engine ground strap is intact and running a jumper cable between the engine and chassis doesn't change anything, so don't think I have a ground issue. New AGM battery. So back to the alternator. Appreciate anyone's experience with running issues related to the alternator. Thanks, Bob
